Constraints on SUSY Breaking in SUSY SU(5) — •Karsten Schnitter — Universität Siegen, Deutschland

Supersymmetric Grand Unified Theories (GUTs) are among the most prominent extensions of the Standard Model. However, the GUT symmetry as well as the SUSY must be broken such that the MSSM emerges at the electroweak scale. We consider the minimal SUSY SU(5) model where the SUSY breaking is parametrized by soft terms. We show that the SU(5) breaking imposes constraints on the soft couplings and discuss the resulting conditions. As these conditions must be met by any SUSY breaking mechanism they provide a tool in the exploration of those models.
